We found remarkable differences in the effector memory (EM; CD45RACCR7) cell subsets of severe pneumonia cases. The frequencies of EM2 CD4+ T, EM3 CD4+ T, EM3 CD8+ T, EM2 DN T and EM3 DN T cells were found to increase in severe pneumonia cases. Consistently, these cells were ...
我们用流式细胞术进一步鉴定了这群活化T细胞的流式表型为CCR7−CD27−CD45RA+CD127lo,即为终末效应记忆性T细胞(terminal effector memory T cells, TEMRA),该群细胞与不良预后密切相关。 综合各因素来看,Cluster 1患者的1年生存...
CD45RA−CCR7−effector/memory Treg subset constituted the majority of Tregs and accumulated in GC. (a) Treg percentage in CD4+T cells in each tissue of patients with GC by gating on CD3+CD4+CD25+Foxp3+cells. Cumulative results from 51 GC patients and 45 healthy donors are shown. (b)...
The memory subpopulation is a heterogeneous pool, and previous studies using two surface markers, CCR7 and CD45RA, led to the following proposed phenotypic classification of human T cells: naïve T cells as CCR7 + CD45RA+, central memory T cells (TCM) as CCR7 + CD45RA– and effector ...
The Yellow Fever Virus Vaccine Induces a Broad and Polyfunctional Human Memory CD8+ T Cell Response cells had a phenotype (CCR7(-)CD45RA(+)) that is typically associated with terminally differentiated cells with limited proliferative capacity (T(EMRA))... RS Akondy,ND Monson,JD Miller,... ...
Therefore CD45RA expressing T cells were initially considered to be naïve T cells that were the precursors of CD45RO+ T cells that contained the primed/memory T cell pool [5]. However the division of T cells into CD45RA+ naïve and CD45RO+ memory T cells was found to be an ...
than of CD8+T cells (Figure 1a). More than 99% of the cells were CD45RO+(Figure 1b) and included both CCR7–effector memory and CCR7+central memory T cells. In contrast, the positive fraction contained a large proportion of CD45RA+CCR7+naive T cells with high potential for allore...

29 These CMV-specific cytotoxic T cells also express CD57 and lack CCR7 and l-selectin.29, 30, 31 To elucidate the basis for the CD8+ T-cell expansion in B-CLL we investigated the composition of the T-cell compartment in patients with B-CLL via extensive immunophenotypic analysis. In ...
